Install 6.20 TN-A Hen and Prometheus ISO loader on your PSP

Thanks to the efforts of Wololo and Liquidzigong, PSP-3000, PSP-2000 with TA-v88v3 motherboard or PSP Go owners can now have custom firmware (well it’s pseudo-cfw.. it’s actually HBL + ISO loader but let’s call it that for convenience’s sake) installed on their PSPs via 6.20 TN-A Hen and Prometheus ISO loader. With the 6.20 TN-A and Prometheus ISO loader, you can now run PSP games off your memory stick for free :).

Requirements for 6.20 TN-A Hen and Prometheus ISO

A PSP-3000, PSP-2000 with TA-v88v3 motherboard or PSP Go with official firmware 6.20 installed. If you have a hackable PSP, I would recommend to install a permanent CFW like 5.50 GEN-D3. If you’re not on 6.20, follow the upgrade guide for your PlayStation Portable on the troubleshooting part of the guide

Your PSP will now load the HBL menu as seen below. Select Hen to load the 6.20 TN-A HEN on your PSP. A bit of warning though, selecting this option will cause your PSP screen to be blank for a moment then reset to the XMB. This is normal so don’t panic.
If you get a “Warning, memory leak!”, again don’t panic, this is normal.

Once you’re back on the XMB, press “select” to make sure the TN Hen menu displays correctly.

all the stuff loaded rite
exept when i go to iso loader and click on the game (NFS SHIFT) , it says LAUNCHING NFS SHIFT , then goes back to XMB . second time i try entering iso loader , it goes to the white PSP screen and shutsdown ………. wat to do ???????

i followed every step and it’s work…exept one thing. when i shut down my psp Go and turn it on after, i cannot lunch the iso loader, i have to repeat the step 4….is that normal, because it’s supposed to be permanent.??
